==Detailed Description==
+
This class is the interface to directional light in the scene.
+
It provides methods to access various parts of a light such as
+
transformation, color, range etc. All methods of this class are
+
implemented by the system. <span style="background:#ffcccc">( Experimental Class )</span> <syntaxhighlight lang="Python">
+
light_object = RLPy.RScene.FindObject(RLPy.EObjectType_Light, "Dir. Light") # use light name to find object
+
  
light_object.SetCastShadow(True)
+
== Description ==
print(light_object.IsCastShadow())

+
#set light shadow strength
+
light_object.SetDarkenShadowStrength(RLPy.RTime(0), 50.0)

This class provides operations for Directional Lights, e.g. whether or not to cast shadows, the light's color, light strength, etc. You must first retrieve a directional light from the scene in order to use these operations.

Description

This class provides operations for Directional Lights, e.g. whether or not to cast shadows, the light's color, light strength, etc. You must first retrieve a directional light from the scene in order to use these operations.

Inheritance

Member Functions

SetCastShadow ( self, bEnable )

Turn on or off the directional light's cast shadow.

light_object = RLPy.RScene.FindObject(RLPy.EObjectType_Light, "Dir. Light")

if light_object:
    light_object.SetCastShadow(True)
    light_object.SetCastShadow(False)

Parameters

bEnable [in] Enable or disable cast shadows for the light - bool

Returns

Success - RLPy.RStatus.Success
Failure - RLPy.RStatus.Failure

IsCastShadow ( self )

Check whether or not the light is casting shadows.

light_object = RLPy.RScene.FindObject(RLPy.EObjectType_Light, "Dir. Light")

if light_object:
    light_object.SetCastShadow(True)
    print(light_object.IsCastShadow())

    light_object.SetCastShadow(False)
    print(light_object.IsCastShadow())

Returns

True if the light is casting shadows, else False - bool

SetDarkenShadowStrength ( self, kTime, fStrength )

Set the directional light's shadow strength at a given point in time (0 to 100).

light_object = RLPy.RScene.FindObject(RLPy.EObjectType_Light, "Dir. Light")

if light_object:
  result = light_object.SetDarkenShadowStrength(RLPy.RGlobal.GetTime(), 50)
  print(result)

Parameters

fStrength [in] The Light shadow strength value - float

Returns

RLPy.RStatus.Success Success
RLPy.RStatus.Failure Fail

GetDarkenShadowStrength ( self )

Get the directional light's shadow strength at a given point in time (0 to 100).

Returns

The light's shadow strength value - float
light_object = RLPy.RScene.FindObject(RLPy.EObjectType_Light, "Dir. Light")

if light_object:
  result = light_object.SetDarkenShadowStrength(RLPy.RGlobal.GetTime(), 50)
  print(light_object.GetDarkenShadowStrength())
